"Until the time comes, I will continue to serve the people of Slidell as their police chief, but I look forward to working with Sheriff Strain -- as much as he will permit -- to ensure a smooth transition," Smith said.

A native of Slidell, Smith is a 28-year veteran law enforcement officer. He has been chief of the Slidell Police Department since 2010.

"From the beginning, our campaign has felt incredible momentum," Smith said. "Challenging an entrenched incumbent took courage, not just for me but for the thousands of supporters who were ready for a change. We're obviously ecstatic at this outcome and look forward to the transition leading up to the oath of office on July 1."

Smith's campaign said he has not announced when he will resign as police chief. His resignation will clear the way for the City Council to call a special election for his replacement.
